Embodiment 1
[0054] 1. Copymaking of decorative base paper
[0055] ⑴ Beating: tear the coniferous pulp board and hardwood pulp board into small pieces and soak in water for 12 hours respectively, use a trough beater to beat the coniferous pulp and hardwood pulp separately, the beating degree of the coniferous pulp is 32° SR, hardwood pulp beating degree is 28°SR. Shake the beaten pulp to dryness and place it in a sealed bag to balance the moisture for 24 hours.
[0056] ⑵ Preparation of filler: Pour the weighed water and titanium dioxide into the frosted disperser, and add the dispersant sodium hexametaphosphate. The amount of dispersant added is 0.4% of the mass of titanium dioxide, the speed of the mixer is set to 20000r / min, and the stirring is performed for 60 minutes. Finally, it was formulated into a solution with a titanium dioxide concentration of 1%.
[0057] ⑶ Slurry mixing: First, the weighed pulp is decomposed, the speed of the standard decomposer is set to 15000r / min, and the tim...

[0092] 1. Copymaking of decorative base paper
[0093] ⑴ Beating: tear the coniferous pulp board and hardwood pulp board into small pieces and soak in water for 12 hours respectively, use a trough beater to beat the coniferous pulp and hardwood pulp separately, the beating degree of the coniferous pulp is 35° SR, hardwood pulp beating degree is 30°SR. Shake the beaten pulp to dryness and place it in a sealed bag to balance the moisture for 24 hours.
[0094] ⑵ Preparation of filler: Pour the weighed water and titanium dioxide into the frosted disperser, and add the dispersant sodium hexametaphosphate. The added amount of dispersant is 0.6% of the mass of titanium dioxide, the speed of the disperser is set to 22000r / min, and the stirring is for 60min. Finally, it was formulated into a solution with a 5% concentration of titanium dioxide.
[0095] ⑶ Slurry mixing: First, the weighed pulp is decomposed, the speed of the standard decomposer is set to 15000r / min, and the time is set to...

Abstract
The invention relates to a manufacturing method of a coating decoration base paper based on gravure. When the decoration base paper is manufactured with pulp, the fillers with different ratio are added; after manufacturing with pulp, the manufactured decoration base paper is coated, dried, calendered and printed by coatings which are prepared by different prescriptions. The manufacturing method comprises the following steps of (1) manufacturing of the decoration base paper with pulp; (2) preparation of the coatings; (3) coating of the decoration base paper in step (1) by the coatings in step (2), and drying and calendering of the coated decoration base paper. The manufacturing method has the advantages that the defect of decreasing of the paper strength due to large filling amount of fillers in the traditional decoration base paper is overcome, the condition of a large loss amount of fillers due to large filling amount and insufficient retention rate of the traditional decoration base paper in the manufacturing process is reduced, and the cost is reduced; by combining with the coating technique, the surface coating suitable for the gravure is formed, so as to reach the purpose of improving the property of gravure.
Description
Technical field [0001] The invention relates to a decorative base paper and a manufacturing method thereof, in particular to a coated decorative base paper based on gravure printing and a manufacturing method thereof. technical background [0002] Decorative base paper is a kind of special industrial paper with good development prospects, mainly used for surface decoration of wood-based panels. In recent years, with the progress of society, human beings have become more and more aware of environmental protection and pay more and more attention to the protection of forest resources. Wood-based panels have a wide range of uses, such as wood floors, cabinet furniture, etc., which are an excellent substitute for wood. Because of the sharp increase in demand for wood-based panels, the demand for decorative base paper for surface decoration is also increasing. The quality of decorative base paper determines the quality of wood-based panel surface decoration and the quality of wood-bas...
